Liam was of course born in 1993 so that's why it's special BUT fans have a sneaky suspicion that it's special for another reason. They're guessing his debut solo album will be named '1993' and that's why he added a copyright symbol to the caption!

Hmmm conspiracy, or legit? We know Liam is happy to mark special events in his life with tattoos, his next most-recent piece was Cheryl's eye (who STILL has not given birth!)... could he also be commemorating his upcoming album? Watch this space...
